Process expert RPC error
Hi, in prevision to download a software modification during a plant shutdown, we launch the "Build" command in the "Application" section, but after 20 min the system server returned these errors:
There's some problem about RPC communication but we can't figure out where the problem is. We already tried to:
clear the VM cache under the VirtualBox folder and AppData\ ... \Process Expert 2020 R2\Vm to force to regenerate the VM
restart the System Server
reboot the hardware machine, shutting down and starting it back
Build the Application thru the VM lauched with the "Refine" command but it crashes after few minutes
Firewall is untouched, nothing changed
Yesterday it "worked" as usual, we were able to edit the application and compile it; in the meantime nothing changed
